Getty Purchases PicScout, Photolibrary

Getty Images has added two more imaging companies to its list of acquisitions: PicScout and Photolibrary.

PicScout is a front-runner in online image use, metadata and licensing technology. With this merger, Getty plans to improve its image identification technology by offering PicScout's tools to their global customer base.

Photolibrary is one of the leading global stock agencies, with more than 10 million images from Europe, the Americas, Asia and the Pacific region. Getty says the acquisition will help meet rising demand for a wider choice of global content.

Since 1999, Getty Images has acquired more than two dozen photo and video agencies, including well-known names like Tony Stone Images, Art.com, U.K.-based Hulton Picture Library, EyeWire, Archive Photos of New York, iStockPhoto and Jupitermedia.
